Step-by-step math

Every number below is computed from the input, nothing is looked up.

1. input
```
H = 20.54°, S = 90.24%, L = 48.24%
```
2. C
```
C = (1 − |2L − 1|) × S = 0.87064
```

3. X

X = C × (1 − |(H / 60°) mod 2 − 1|) = 0.29805   (H / 60° = 0.3423, sector 0)

4. m
```
m = L − C / 2 = 0.04708
```

5. (R′, G′, B′) + m

(R′, G′, B′) = (0.87064, 0.29805, 0.00000)
R = round((0.87064 + 0.04708) × 255) = 234
G = round((0.29805 + 0.04708) × 255) = 88
B = round((0.00000 + 0.04708) × 255) = 12

6. RGB → HEX
```
#EA580C
```
